.SH DESCRIPTION
\fBcsx_MakeDeviceNode()\fR and \fBcsx_RemoveDeviceNode()\fR are
illumos-specific extensions to allow the client to request that device nodes in
the filesystem are created or removed, respectively, on its behalf.
.SH STRUCTURE MEMBERS
The structure members of \fBmake_device_node_t\fR are:
.sp
.in +2
.nf
uint32_t        Action;         /* device operation */
uint32_t        NumDevNodes;    /* number of nodes to create */
devnode_desc_t  *devnode_desc;  /* description of device nodes */
.fi
.in -2

.sp
.LP
The structure members of \fBremove_device_node_t\fR are:
.sp
.in +2
.nf
uint32_t       Action;          /* device operation */
uint32_t       NumDevNodes;     /* number of nodes to remove */
devnode_desc_t *devnode_desc;   /* description of device nodes */
.fi
.in -2

.sp
.LP
The structure members of \fBdevnode_desc_t\fR are:
.sp
.in +2
.nf
char           *name;           /* device node path and name */
int32_t        spec_type;       /* device special type (block or char) */
int32_t        minor_num;       /* device node minor number */
char           *node_type;      /* device node type */
.fi
.in -2

.sp
.LP
The \fBAction\fR field is used to specify the operation that
\fBcsx_MakeDeviceNode()\fR and \fBcsx_RemoveDeviceNode()\fR should perform.
.sp
.LP
The following \fBAction\fR values are defined for \fBcsx_MakeDeviceNode()\fR:
.sp
.ne 2
.na
\fBCREATE_DEVICE_NODE\fR
.ad
.RS 22n
Create \fBNumDevNodes\fR minor nodes
.RE

.sp
.LP
The following \fBAction\fR values are defined for \fBcsx_RemoveDeviceNode()\fR:
.sp
.ne 2
.na
\fBREMOVE_DEVICE_NODE\fR
.ad
.RS 27n
Remove \fBNumDevNodes\fR minor nodes
.RE

.sp
.ne 2
.na
\fBREMOVE_ALL_DEVICE_NODES\fR

.RS 27n
Remove all minor nodes for this client
.RE

For \fBcsx_MakeDeviceNode()\fR, if the \fBAction\fR field is:
.sp
.ne 2
.na
\fB\fBCREATE_DEVICE_NODE\fR \fR
.ad
.RS 23n
The \fBNumDevNodes\fR field must be set to the number of minor devices to
create, and the client must allocate the quantity of \fBdevnode_desc_t\fR
structures specified by \fBNumDevNodes\fR and fill out the fields in the
\fBdevnode_desc_t\fR structure with the appropriate minor node information. The
meanings of the fields in the \fBdevnode_desc_t\fR structure are identical to
the parameters of the same name to the \fBddi_create_minor_node\fR(9F) \fBDDI
\fRfunction.
.RE

.sp
.LP
For \fBcsx_RemoveDeviceNode()\fR, if the \fBAction\fR field is:
.sp
.ne 2
.na
\fB\fBREMOVE_DEVICE_NODE\fR \fR
.ad
.RS 28n
The \fBNumDevNodes\fR field must be set to the number of minor devices to
remove, and the client must allocate the quantity of \fBdevnode_desc_t\fR
structures specified by \fBNumDevNodes\fR and fill out the fields in the
\fBdevnode_desc_t\fR structure with the appropriate minor node information. The

.RS 28n
The \fBNumDevNodes\fR field must be set to \fB0\fR and the \fBdevnode_desc_t\fR
structure pointer must be set to \fINULL\fR. All device nodes for this client
will be removed from the filesystem.
